(More customer reviews)I might be a day late and a dollar short but as long as you stand the product up on it's side, there is no heat issue. If you either wall mount or mimic a wall mount by standing it on the side with the ports facing up you won't have a heat issue at all. If you lay it flat, you will have heat issues. I tried it standing up with the ports face down but it got hot. The vents for the heat to escape are on the side with the ports so if you face that side up then there is no heat issues.
